Taxonomic note
Eclectus Parrot Eclectus roratus has been split into Moluccan Eclectus E. roratus, Sumba Eclectus E. cornelia, Tanimbar Eclectus E. riedeli and Papuan Eclectus E. polychloros. Extensive museum work confirmed the four groups proposed as species on molecular data (Braun et al. 2017) do exceed the threshold of 7 under the Tobias criteria (Tobias et al. 2010) and are therefore accepted as species.

Population justification: Eclectus riedeli is thought to have similar population densities to those recorded for E. polychloros (11 individuals/km²). The population of E. riedeli is therefore estimated at 10,000-15,000 individuals, which equates to 6,600-10,000 mature individuals.

Trend justification: E. riedeli is thought to be declining slowly due to continued habitat loss through deforestation and local trade. The species is often observed at the edge of the extensive remaining forest suggesting that over the whole of Yamdena and Larat the rate of decline is relatively low (eBird 2019), large areas of Yamdena have limited access to people even today. Rates of deforestation within the range of E. riedeli are approximately 8% over three generations (Tracewski et al. 2016). The threat posed by trapping and trade is also relatively low. Whilst the species is locally traded, with individuals noted as pets on Yamdena, it does not appear to be exported from the island in large numbers (Bishop and Brickle 1999).
